Paragraf tamamlamaSoru #8439
Complete the paragraph with the most appropriate option:
The James Webb Space Telescope (JWST) operates primarily in the infrared spectrum of light. This choice of wavelength is crucial for investigating the earliest epochs of the cosmos. ---- Because cosmic expansion stretches this ancient visible and ultraviolet light into longer infrared wavelengths, only an infrared observatory like JWST can unveil those first stellar nurseries.
